The effects of different factors during the preparation on the carboxyl content of CA- β-CD were discussed and the optimal synthesize process was obtained: the mol ratio of catalyst NaH PO (SHP), citric acid and β-cyclodext- 2 2 rin was 1∶2 ∶1, material to liquor ratio was 1∶0.6, and the reaction was carried out under 100 ℃ for 1 h. The fin－ ishing effects of the cotton fabric were compared, the results showed that the weighting percentage, whiteness and breaking strength of the CA-β -CD derivative grafted fabric were higher than that of the citric acid mixed with β-cyclodextrin system.
